Improvement of identity-based authenticated key agreement protocol

摘要：

The security of a recently proposed ID-based authenticated key agreement protocol was analyzed, and an enhanced ID-based authenticated key agreement protocol is presented based on the previous work, a malicious PKG (private key generator) can still obtain all of the agreed session keys, that is, it doesnt provide PKG-forward secrecy in escrowless mode.Aiming at the security flaws of an existing Idbased key agreement Protocol and a key agreement Protocol for multi-trustdomain proposed based on the new variant mode of ID-Base public key infrastrueture(PKI), an improved scheme is proposed.The new scheme can avoid excessive power of KGC to make up the security flaws in the original protocols, which has a higher level of security.The new schemes have many properties such as equal contribution; non-key control; against man-in-middle attack; etc.
